I am sure you were just generalizing and know what you are doing but for the sake of those not as versed in network design...

Keep in mind that the values you noted are text book network values. Those are based on electrical parameters and not acoustic output so even that won't work correctly in the end.

That said, if you are highly skilled and want to do it, I say go for it

I wasn't suggesting "dropping in" inductors and capacitors into the existing network. I was suggesting making a new "network" using cheap parts (the "network" is nothing more than an inductor in series with the speaker, and a cap in parallel for a 2nd order XO). I'm not sure what the individual impedances are in the Axiom speaker, but if they are 4 ohm, you would only need to buy a .45 mH inductor and a 14 microfarad cap.

I know, and in re-reading my posts they may have come off as argumentative. That was definitely not intended, it's sometimes hard to get intended emotion across on the internet. My interest is than of an engineer, as well as an audiophile.

What really peaked my curiosity was that you basically changed 2 things, the quality of the components, and the xo setting. I wanted to see if only changing one thing (the cheap thing - the xo setting) would make a noticeable quality difference. That is to say, how much of the improvement is from the cheap change, and how much from the more expensive change.

I think it's cool to tweak things to make them sound better; after all, we all share the common love of music.

Now this would be really cool is some measurments and double blind testing with a pair of ninja modded M22v2 (more expensive components), a pair of modded M22v2 with cheaper components and a pair of stock M22v2 as a control.

That would be the best way to go about it, but at a total outlay of something north of $2000, I'm not seeing it happening by a private party. And there don't seem to be enough M22 owners in a given geographic area to try it.

Very good point. The only way I can see this happen if someone decides to purchase the network and ship it to Ian. The most meaningful measurments and testing in my eyes would have to be done by Ian and not a "private party".

No matter what this will not be happening any time soon considering these networks take 3-6 weeks to ship. All this hype will probably be blown over by then and will be forgotten.

Ninja, I think it would preclude some objections if you made the comparative graphs on your site the same scale. For many of them, the scale for the stock M22 is 75-100 db while the modified graph is 70-95. If you're going to try to prove things by measuring them, I think it is helpful to be as accurate as possible.

While I'm sure that higher quality (i.e, tolerance) components will make a difference in the sound, I was willing to bet that the xo setting made the more noticeable difference. Again, even changing the xo setting is a matter of taste, as long as the drivers are capable of the adjusted frequency.
